Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Bulk organic carbon in the studied rocks is anomalously depleted in 13C, with δ13C values between -32‰ and -50‰.

    “Consistent with earlier work (1,10,39,40), the bulk organic carbon was found to be anomalously 13 C-depleted, with δ 13 C values ranging from -32‰ to -50‰ (Fig. 2 and SI Appendix, Table S5).”

  • The HyPy hydrocarbon δ13C values reported here are the first compound-specific isotopic measurements in agreement with strongly 13C-depleted kerogens (bulk δ13C < -39‰) of the Neoarchean.

    “The HyPy hydrocarbon δ 13 C values reported here are, to our knowledge, the first compound-specific isotopic measurements that are in agreement with the strongly 13 C-depleted kerogens (δ 13 C bulk < -39‰) of the Neoarchean (1,10,39,40).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
